NEW JERSEY, A CORPORATION or NEW JERSEY HEELING MACHINE Application Bled February 18, 1928. lSerial No. 255,436.

This invention relates to heeling machines, and particularly to the work supporting'and presenting mechanisms of such 'machines'.

An object of the invention is so to improve the arrangement of the shoe Supporting, pressure applying, and heel holding elements of heeling machines as to facilitate theinsertion into the machine of the work parts and the accurate relative positioning and attachment ofsuch parts to each other.Y

In a well known and widely usedV type of machine, the lightning heeler, the shoe supporting j ackis arranged to slide from an accessible, work receiving position to an operating position beneath a stationary nailing die, the lower face of which engagesand applies pressure to a heel supported in a-heel holder located between the die and the jack, in fact practically against the lower face 4of the die. The heel holder facing downward and being below the normal line .of vision of the operator, the heel is inserted principally by the sense of touch. In accordance with the present invention the nailing die is made Vmovable froma heel receiving position, in which its work engaging face, with thef heel holder thereon, is eX-v posed to view and is easily accessible, to. a heel nailing position, which it occupies while the heel attaching nails arelbeing driven. Preferably the die isso connected to the movable shoe supporting jack of the heeling machine that the die derives its movement from the movement :of the jack and, in this connection, a feature of the invention resides in an improved organization of mechanism of they character described in whichthe nailing die is movable about an axis passing through saiddie. By virtue of this the great strength necessary in lheeling machines is secured without the sacrifice of compactness which would be en-v tailed other arrangements.

Furthermore, it is essential,` foi` obvious reasons, that the holes in the die be in exact alinement Vwith the nail' drivers when the drivers are operated to enter said holes and drive the nails, but a slight amount of lost motion in the connections between the jack and the die will destroy the accuracy of the alinement produced by positioning the jack,` toa dangerous eXtent.` Another feature of the invention, accordingly7 consists in the provision ofa fixed abutment arranged to be' engaged directly by the die to determine'accurately thenailing position of the die. v`The determinationof thenailing position of the. die is thus made positivevand danger of inexact positioningof the die, by reason of looseness resulting Vfrom -wear' or any other cause, is eliminated.; Inthe illustrated machine the connections betweenvthe'jack and die are made suiiicientlyyieldingto permit the movement of the die to be stopped by the abutment before the end of the inward movement of the jack, assuringthatthev die will unfailingly engage the abutment and be properly positionedfor use.

A further feature ofthe invention, con-I tributing lto accuracy and certainty in-,the functioning of the mechanism, consists in a normally inoperative lock arranged, to co-op- Y erate with the nailing die to lool; it in nailing position, `combined with ymeans l,whereby movement of the jack causes the-lock to operate. An efficient embodiment of thisjfeature is shown inthe accompanying drawings wherein is illustrated a machine in which the nailing die lock'is connected to and Operated by a lock actuator constituting aback gage arrangedto be engaged by thefjacked' shoe when the :jack is moved into operatingposition. v

These and other features andadvantages of the' invention will be better understood and appreciated Yby `reading the following detailed description yof one embodiment thereof in connection with the accompany-` ing drawings,.in which, l i p v Fig. 1 is a view in side elevation,partly in section, of-heeling machinev mechanism embodying the invention, thefpartsybeing shown in work receiving position;l K

Fig. 2 is a similar view showingthe` parts in operating position; and` l n Y g Fig. 3 is a view, partly in elevationand partly in section, looking from the front of the machine. f f 1 v The machine comprises ,the usual station-k ary side rods 10 (Fig, 3) rigidly spaced herein illustrated reference may be madeto United States Letters Patent No. 446,885,

grantedjFeb. 24,1891, 'upon application ofy Joseph H. Pope.

Horizontal i inwardly extending trunnions j' 16 are mounted upon the side rods 10,assliown in Fig. 3, and constitute supportsy about which a nailing die 18 is adapted to" nieve'L around a horizontal ypassinggthroughH said die. The construction and arrangement are such that the die 18 is movable, `about the aXis of the trunnions-16 from the position shown in'Fig; 1, in which the heel engag- 1 ing face of thedie faces outward and upward` toward -tl'iefront ofi the machine, to the position shown in Figs. 2 and 3, in which the heel engaging face of thef die faces downward.

A shoe supporting jack 20 is mounted for pivotal'movement about trlunnions 22 upon the cross'head 14j from the workreceiving position lshown-in Fig. 1, where itis accessi- Y ble forthe jackinglorreinovalof a shoe,

tothe operatingposition -shown in Fig. 2, whereitis: beneathtlie nailing die. The

jack is, as usual, moved into and out of the machine byhand. l

In order to effect lthe desired movements of the nailing die between work Yreceiving and operating positions, 'movement transmitti'ng connections are provided between the movable jack vand the movable die. As hereinshown these connections comprise a two-part link-213, one end of whicliis pivoted to the nailing die 18at 24-a nd the other end of which is pivoted to the jack member at 26. yThe nailing die is recessed, as shown at 25, to avoid interference between the die and the link 'in' operation.vv The two sections of the link are telescopically arranged.,` as shown in Fig. 1, a compression spring 28 being interposed between the two sections of the link and permitting a small-amount of yield lengthwise thereof. The rear face 30 of the nailing die18,is arrangedto abut Vagainst the frontface 32 vof a 'stationary bracket 34 to limitl positively themoveinent of the nailing; die, as it'fr'e'aches4 operating position. From the foregoingit will be ap'- parent that movement of theY jack 2O Yinto and out of the machine Awillfbe transmitted by the connecting'link 23'to the nailing ldie andwill cause movementk of the die between the two positions shown in Figs; 1 andI 2.-

A threaded 'adj ustm'ent v36T permits variation of the length of the link 28, which is so determined that the: nailing die engages and is stopped by the surface 32 just before thejack reaches the rearwardlimit of .its movement, the spring y28 yielding topermit the `remainderof 'such movement.

In order to insure accuracy in the operating position of the nailing die and to avoid any possibility of moving when pressure is. applied there are provided taperedwlocking. boltsv 38""whichl enter correspondingly ta- .peredholes 40 in the rear face 30 of the die. Y

The bolts are Aslidably mountedmin lguide ioles formed the :bracket l34-andr Parefactuated; by arms42 secured` to 'a'rocli shaft 44 to ,which is also securedaudependiiig lever 46.VV The lever 46-tengages thefrear face of a nut 48ithreaded upon a horizontally movable's'cre'vv 50, the limits of movement of the .Screwbeing-.determined by spaced, Stationary uprights 52, 54 through which the Screw moves; Tothe4 frontend of the ,screw 50 is pivotedl aguide plate 56,upon: which a. backgage is vertically slidable. The said backgage islsuppoited by a bar-62,*the lower end of y .whichhis .pivotedat 64 to aubracket 66 bolted toand movable with the cross head 14. The back gage 60, therefore, moves.up

and, by-virtue ofthe pivotal ,connection 64, can i-be movedl rearwardl by the jacketed shoe to a position deter-mined by.y theadjustment of the-.nut48 upon thescrew V50. Also secured to '.ft'he. rock shaft 44l is. a forwardly disposed Variii..-68 which, is connect'ed-by-a link 0 tqarocker .arm (2 mov.- able-aboutv ka stationary. pivot 74. pull spring. 7 6, connectedto the. linkA 70 Aand the bracket.34, tends,A normally to elevatewtheg link fand, consequently, to move. the locking bolts 38 rearward and the back gage 60 for- The. rockerV arm.72.is connected to and operatesa Lclutch, stopv rod 78, thelower end of which co-operates with a. dog 80 to Vpre-y ventroperlation of the clutch engaging shaft 82 to apply powerfto the machineywhen the shoeJ is not in operating position therein, in a manneralready known to those skilled in theiartf.: K,

. A lheel holder siiitablefor the'type of heel to be'V attached is secured tothe heel engaging face ofthe nailing die 18 ,and partakes of ther. movements `ofg'the latter. The ,present machine is illustrated as',l equipped to attach a heel consisting of an' assembled rubber top lift 80` land abas'e 82 and the-holder consists i of. a ring or a-,form 84, in `which therubber heel section fitsclosel'y, held in lplace on' the ino lower -faceoftlie'gnailing die by a flange 86 'y and a spring actuated latch 88.

rlhe machine is' vnormally stopped. with the mechanism disposed as Vshown in Fig. l', the heel holder facing outward, and upward toward the operatorseyes andaccesstothe holder being entirely' unobstructed. A lasted shoe 9() is vplaced upon the shoesupporting jack and` aheel is inserted in the heel holder, against the faceV of the nailing die..v The jack is now moved rearward until the shoe engages and is stoppedy by thefrear gage 60. The inward movementof the jackejffects a moveconnections between the jack and ment of the nailing die and heel holder to the position shown in Fig. 2 where the heel is supported above the shoe ready to be pressed thereon. The last part of the inward movement of the jack has, as hereinbefore described, caused the screw 50 to be moved rearward and the lock 38 to be op` erated to lock the nailing die in operating position; it has also caused the rod 68 to be retracted, unlocking the shaft 82 and permitting the clutch controlled thereby to be engaged to eect the power operation ofthe heel attaching mechanism of the machine in the usual manner. When this operation is complete and the pressure is released the operator returns the jack 20 to theposition shown in Fig. l, the nailing die 18 being unlocked and also returning to work receiving position without any attention from the operator. The shoe, with the attached heel, is now removed from the jack and the ma chine is ready for a repetition of the operation upon another shoe.
